Many years ago 'Practical Electronics' magazine ran a project called, I think, 'Sound Bender' which incorporated ring modulation with a variety of other effects (envelope shaping etc.). I built it, and it worked very well, especially for such a simple device. You'll have to search the archives for the article though - late '70s, early '80s I think.

Hi.

Take a look at this one http://www.generalguitargadgets.com/...142&Itemid=169
Great documentation and also a good Page for DIY-Effects-Builder.

Sorry Mike - it's a long time ago, and I don't even have the unit any more. Your local library might be able to find the article though.
Alternatively, you could experiment with doing it the old-fashioned way, using transformers (old transistor o/p txrs or similar should do OK for experimenting at least).

Hi All
I would love to build that Practical Electronics Sound Bender-does anyone have the schematic and associated mag. I had it in my collection-but lost it ina move!!
And I'd never even built it
It's a pinky red fold out out insert.

Many thanks

Default PE 74 Sound Bender

Hi
I now have that soundbender pullout, thanks to a very kind chap called Allan Winstanley. So anyone who would like a copy, please PM me
It looks like you could substitute valves in the circuit, as its just a phase splitter, (easily implemented for tube)with phase of 1 leg controlled by a drain source junction of a FET (could replace easlily with tube?) with the 2 phases summed together. The audio goues into the input to the phase splitter-then the control input(env gen, LFO VCO, etc) goes into the gate of the FET-will post schematic soon

Default Add tubes to the Sound Bender

HI
Remeber the Practical Electronics Sound Bender pull out that had a modulator circuit which was basically an audio phase-splitter with one phase going directly to the input of a summing amp and the other going with a FET as a variable Voltage cont resitor to grnd-and then on to the other summing amp input?
If you put a synth, gtr, mic input , whathaveyou, into input one-you can get a ring mod effect by putting an oscilator (audio) into the second input
I though of "tubifying" this-see below.
But, anyone got any ideas on how to succesfully replace the FET with a tube?

You cant get simpler than this - two audio transformers and a bunch of diodes. You could use these transformers < Eagle LT44 Radio Interstage Audio Matching Transformer on eBay (end time 27-Jan-11 17:20:17 GMT) > with signal diodes.
